“It is that kind of across-the-board fandom that represents Rush and its legion of dedicated and intensely loyal fans, among them a slew of artists and celebs who turned out for the Forum show, including the Red Hot Chili Peppers’ Chad Smith, Tool’s Danny Carey, Foo Fighters’ Taylor Hawkins, (all there to honor legendary Rush drummer Neil Peart), Robby Krieger and South Park creator Matt Stone. At one point during “Red Barchetta,” Jack Black — who was surprisingly left alone on the floor — danced around playing air guitar. Indeed, if there’s one concert where air playing is encouraged — air guitar, air bass, air drums — it’s a Rush show.”
